Instead of the rather specific Lätkäzombit-adventure, the example game that comes with the engine could a very plain "template" adventure, without story, real characters and just "insert witty retort here" -style texts. All the features should be featured, of course.
The template adventure should be - as much as possible - a tutorial for creating new adventures. Every existing feature should be in the template adventure.
